RS-485 is used in basically connecting the temp sensor or thermostat in the room to the master controller. With an RS485 interface, the FieldLogger could act as a Modbus RTU master and read registers from other slaves, and as a master, it was able to read and log up to 64 registers from Modbus slaves. A precision plastic hybrid 10K-ohm potentiometer delivered a voltage divider output signal that was linearly proportional to the travel of the spring-loaded measuring cable, based on the movement of the grain bins, which the FieldLogger then read and recorded at 1 reading an hour. After having defined the type of instrument best suited to the needs, if the measurement is performed by indirect insertion, the accessories of the measuring system, such as current and voltage transformers must be chosen with care. The recorder offers a fast sampling rate within 200msec for all channels and high accuracy with up to 18 universal input channels to connect to a variety of sensors commonly used in lab environments including DC voltage output from specialty sensors and thermocouples/RTDs to log temperatures with extreme precision. Larger quantities will ship in a flat rate box.

Kits are $16.50 each, and ship in a padded envelope. If not only the electrical parameters are to be monitored, but also the energy consumption, measuring instruments which also have active and reactive energy metering should be selected. Some measuring instruments have bar indicators that show the current level as a percentage of the set full scale. In a three-phase system, instruments can be installed that measure the single electrical parameter, one per phase, or a voltmeter and a current can be installed with the voltage and current switches, allowing the measurements to be displayed in sequence. The sizing of the measurement system begins with knowing the main parameters of the plant; in particular, from the characteristics of the protection switch, the type of distribution system, the rated current, the rated voltage and the type of busbar can be known. Multifunctional instruments can be used in different distribution systems. The instrument must be selected according to the type of distribution system. If your system is unreliable, flakey, or blows up from time to time, you need to talk to us. The product engineer then connected the FieldLogger to a Celesco SM2 miniature string pot to detect and measure linear position and velocity over time.

The Novus FieldLogger functioned as a versatile yet powerful data acquisition and SCADA system which the product engineer found simple to use. GSI Grain Storage installed a Novus FieldLogger data acquisition system in a grain storage bin that was repeatedly loaded and unloaded into the storage floor area to measure the separation of the floor sections. CAS DataLoggers recently provided the datalogging solution for GSI Grain Storage in Assumption, Illinois, the world's largest manufacturer of steel farm grain bins, commercial storage grain bins and grain silos, as well as grain dryers and material handling systems including grain bin sweeps, spreaders, chain loop systems, commercial bucket elevators and conveyors. CAS DataLoggers together with high-quality manufacturer Brainchild has the solution with the VR-18 Paperless Chart Recorder, a high resolution (true VGA, 640x480 pixels) 18-channel data logger featuring an infrared detector, plug & play I/O card, high flexibility, and user-friendly operation, all in a compact size. 240 V ac/dc power and was configured, monitored and downloaded its data via USB interface, also featuring automatic data downloads via USB flash drive. USB Serial - The ANC-6204 multi-interface USB adapter provides RS232, RS422/485 or TTL/CMOS in one converter. Able to handle multiple inputs, the datalogger provides useful information for experiments involving the heating of various liquids at a variety of volumes.

This provides a wide range of interface possibilities. Capable of performing mathematical operations in the input channels, this high-speed reading and logging device utilized a 24-bit A/D converter enabling up to 1000 samples a second and a suite of connectivity options including a 10/100 Mbps Ethernet interface that allowed for access through a browser (HTTP), FTP (client and server), e-mail sending (SMTP), SNMP and Modbus TCP. The only possible reference is the reading of the displayed value, for example, of the current. This high performance and high connectivity equipment also offered personnel easy configuration and operation to get the project underway as quickly as possible. 2) the GSM version also allows you to indicate a possible PIN (leave blank if there is no PIN) and the operator's APN (possibly you can search for it on Google). It is interesting to measure the humidity of the ground, but we have also thought about other things; and then we have TXtemp to measure the temperature (one of the uses of TXtemp is in association with SuperClock), and for practically any type of measurement we have TXdata (RS232, RS485 ModBus) - which can be connected to thousands of existing third-party professional RS232 or ModBus meters (and there is something for all needs: temperature and humidity meters, anemometers, voltage meters, energy, light meters, water meters, presence sensors, brightness sensors, soil humidity sensors, etc. ; practically all professional meters are available in ModBus or RS232 standard; and not just meters).
